CORN CRIB CAP Filed May 22, 1957 INVENTOR. Freo/ Travb H T ORNEY United States Patent CORN CRIB CAP Fred G. Traub, Sioux Falls, S. Dak., assignor to llaven Industries, Inc., Sioux Falls, S. Dak., a corporation of South Dakota Application May 22, 1957, Serial No. 660,862

1 Claim. (Cl. 98-55) My invention relates to a corn crib cap.

An object of my invention is to provide a cap for use with corn cribs of the wire and slat type principally, which will elficiently seal the crib against weather, and yet at the same time will provide a ventilating feature which will insure the circulation of fresh air throughout the corn mass.

A further object of my invention is to provide a sealing plastic member which is impervious to weather conditions, and to further provide means whereby the plastic or cap can be pulled downwardly at desired intervals as the corn mass settles in the crib.

A further object of my invention is to provide an arrangement which is relatively easy to install and which will remain in fixed position regardless of adverse weather conditions.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter morefully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure l is a forward elevation of a corn crib with my cap secured thereto,

Figure 2 is a plan view of Figure 1,

Figure 3 is a sectional view of the ventilator taken substantially along the lines 33 of Figure 4, and

Figure 4 is a sectional view of Figure 3 taken along the lines 44 thereof.

I have used the character 10 to designate generally a corn crib which in the present instance is made of snow fencing and in which a plurality of vertically positioned slats 11 are bound together by means of the circumferential wires 12 at vertically spaced intervals, and wherein the complete crib can be made up of three or more sections of standard snow fencing suitably joined together.

The principal objective of my present invention is to provide a highly efiicient arrangement which will protect the corn and yet will allow it to be aerated or ventilated throughout its entire mass.

I have used the character 13 to indicate a substantially disc-shaped sheet of weather-resistant, water-impervious material such as certain plastics or the like, this sheet having a central opening at 14, and received within the opening 14 is a cylindrical tube 15 which is secured at 16 to the disc-shaped metal member 17 having the opening 18, the opening 18 communicating directly to the interior of the tubular member 15.

Secured as at 19 to the inside of the member 15 are the vertically positioned legs 20 spaced as shown in Figure 4, these legs having the lower horizontal feet 21, and the upper angularly bent portions 22, which are bent into the portions 23, the portions 23 being secured to the upper cone-shaped member 24.

Resting upon the plastic sheet 13 is the relatively stifi circular wire member 25 which is hookedtogether as at 26, and tied at 27 to the wire 25 are the radially positioned tie-lines 28 which pass radially along the plastic or cap member 13, and which are then tied as at 29 to either the slats or preferably the wires 12, these tie-lines being tied down sufliciently to provide a relatively snug arrangement.

The feet 21 of the legs 20 will rest upon the top-most ears of corn as shown in Figure 3, and it will be noted that the ring 25 together with the tie-lines 28 will securely hold the entire cap in place and in firm position. A wire 30 is then tied about the portion 31 of the plastic cap 13 which extends aroundthe upper end of the crib, and it will be noted by virtue of this arrangement that a tight enclosure is provided to protect the corn.

The spacing of the feet 21 relative to the disc 17 insures that suflicient space will be provided between the top of the corn and the plastic sheet to allow ventilating air to pass upwardly throughout the mass of corn substantially in the direction of the arrows 32 (see Figure 3) thence.

As the corn settles, the tie-lines can be untied at 29.

and retied at lower points if desired, and in this manner the cap can be pulled down from time to time during settling of the com, the wire 30 being first slightly loosened if necessary.

=It will be noted that the cone 24 permits protection against rain and other weather conditions and yet allows the ventilating or breathing feature wherein the air will pass through the entire mass of corn as explained above.

-It will now be seen that -l have provided the advantages mentioned in the objects of my invention with further advantages being readily apparent.

Some changes may be made'in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim any modi fied forms of structure or use of mechanical equivalents which may be reasonably included within its scope.

I claim as my invention:

A corn crib cap comprising a sheet of weather-resistant pliable material adapted to cover the top of corn in said crib, a ventilating unit, said ventilating unit passing substantially centrally through said pliable material, said ventilating unit including a plurality of spaced legs, said legs including feet adapted to rest upon said corn, said legs providing a space between the top of said corn and said pliable material, to permit complete ventilation through the mass of corn in said crib, said ventilating unit including a substantially cylindrical tube attached to said legs, the upper ends of said legs being spaced from the top of said tube, a substantially conical member attached to the top of said legs, said material having an opening receiving said tube, a substantially circular disc attached at the bottom of said tube and including an opening communicating with said tube, the central underside portions of said material being adapted to rest upon said disc, a ring receiving said cylindrical tube and resting upon said sheet, a plurality of radially positioned tie-lines attached to said ring and passing radially over said material, said tie-lines being adapted to be attached to the walls of said crib.
